Virtual host config question (i think)

Running Drupal 7 on a WAMP stack and think i'm having server config issues. I've set up my vhosts and hosts files for my server (localhost) and my site, uncommented Include conf/extra/httpd-vhosts.conf in the httpd.conf file and get to my site's home page - which is displaying weirdly as if a lot of css is missing/wonky, AND every link from the home page breaks because it's trying to send it back to the local server. What in the seven hells am i doing wrong?

 

I would guess it's looking for files in the wrong places. Since I'm not familiar with Drupal 7 setup, I can't really help you too much there, but I'm assuming you're using something like http:// mydomain instead of http:// mydomain.something for you localized testing?
I would have a look at the plain html source when looking at the frontpage, and check all the includes and links, to see where they're sent or fetched from - I'm guessing somewhere in there you have a wrong setting for local filepath or mixing localhost into the mix.
